2 ClalmS.. (CL 10039) This invention relates to improvements in fruitr juice extractors and has particular reference to an apparatus wherein fruit is fed to cooperating compressor elements which are automatically discharge 4the compressed fruit therefrom. i

An object of the invention is to providean l struction inwhich a. fruit Vis compressedby the-.1 I action of two compressor elements.' one of which@ is thereafter operated to discharge the compressed fruit therefrorn. y 1 L Another object is'torcintrol,A frorn" a single source of power', .the extraction of' juice from a I fruit by they cooperation of compressor 'elementsf 1.5 the discharge vof the l compressedxfruit` `fr om'said n elements, and .the dispensation of measured' quan--v tities ofthe extracted juice intoa series'o'f indiV vidualreceptac1es. y w

The .above and other objectsvwill appear more. clearly from the following 7 detailed description when taken in connection with the accompanyf' ing drawings which illustrate a preferred embodig. ment of the inventive idea.`

Fig. 4 is an enlarged vertical section through' the reservoir inwhich thejuice from extracted fruit is accumulated and-from whichsaidjuicej is dispensed in measured quantities, and Fig. 5 is a fragmentary detailed sectional view j315 'juiceinto a seriesof lndividualreceptacle's. l

Briefly, the invention isy shown. as 'comprising a frame-work I above'which is supported, by a standard I I, a curved delivery chute I 2 into which fruit, such as oranges,` are fed randl advancedby the inclination ofthe chute, to an escapement mechanism generally indicated by the numeral I 3.` This mechanism operates'to `deliver the oranges, one by one, to a'pivotally mounted compressor element-l |4 which ycooperates with a vertically movable compressor element I5 to compress the fruit within the element I4 and thus extract the juice therefrom. `At the termination of such compression operation and subsequent separation of the compressor elements, the element I4 is swung aboutits pivot to the dotted line position of Fig. 1 to deposit the pressed fruit into the discharge chute I6, after which said element I4 is mounted upon theshaft I9.- .l I The *escape'ment mechanism I3 is supported,

f by V'a bracket -3I,' `1near the youter or delivery end ofthe chute'` I 2',and is controlled from the shaft 1 I9 in lsuch manner that when the'parts are operated from4 the positlonof Fig. 1ra single' fruit Will' bereleased from the chute so that it willv fall into thecompressor elementI I4.

f'un'prixnemover, suchas an electrical vmotor 23 supported l.uporrthe frame 19, is employed to lperform the-various functions'described while the apparatus is' in-'operation The drive from the motor isfthroughthe endless belt 24 to the countershaft Z'Sv'niOuntedin-bearings 26 andIhaving thereon, if desired a clutch conventionally shown f at 21": an`da provided', vvith-L a control leverf 21a:- The shaft. 25 is; als'of coupled to a gear reduction 28 offstandard construction tofoperate a-*sm'all o gear 29 which meshes with the. rriaster. gear 30 Said mechanism comprises a rocker arm 32 p ivoted intermediate its ends at the upperfend ofthe ,bracket 3| and having connected to its' pivot 33 a link 34 to which isjoined the yupperfend of a rod 35. The lower end of said rod V35isco1v1nected to one end of the and joined to theotherend of. s'aid,a.rm 3B is a. Vlink 31 the lower end of which carriesa rollerV 39 Y Lhaving a bearing ina cam 39 fixed upon the shaft 1 rocker. arm' 36 supported by/,the'frame work I9,

I9. `Horizontally disposedy and adjustable cross arms 40 are secured at 4I adjacent the upper end of the bracket 3| and the'outer'extremities of i said arms are provided withguides 42 in which are vertically slidable rods 43. having pin and slot connections at their upper ends with the rocker 32. Each of the rods, 43, 44 is made in .,that of the arms 4U, permits the escapement mechanism to be adapted to fruits of diierent sizes. The lower ends of the rods c3, de termihate in yokes 41 carrying rollers 53 for alternate engagement with fruit as it is fed downwardly in the chute Ijl. As shown in Fig. 2 the rod 44 is lowered so that its rollerfli is positioned in the path of a fruit '49 to prevent further progress of said fruit toward the compressor element It. When the escapementl mechanism is operated by the cam 39, the rod 41| is raised and the rod 53 lowered so that the roller of the latter rod will prevent movement downV the chute of the fruit in back of the piece of fruit 4Q, and the raising of the rod 44 will release the latter piece of fruit so that it will roll down the chute and into the element I4. Then, upon the restoration of the escapement mechanism to the position of Fig. 2, the. raising of` thelrod permits the next piece ofjiruit to roll` until it contacts the roller Q8 of the rod M.- j l y n The fruit, released from the chute l2 by theescapement mechanism enters the element I6 the) bodyl of .which is cylindrical in formation and is provided `with a perforated bottom 50 which is centrally depressed to form a. cavity I to better center the fruit within said` element. preparatory to -its compression.v Said element is seated in its operative position upon the upper end of a sta tionary funnel 52 the lower end'oi which is detachably connected to thel reservoir I1 by wing bolts '53. lWhen a rfruit has been deposited into the element Ill the vertically movable compressor element I5l is lowered, in a manner to presently appear, to cut and compress said fruit so that the juice will be' extracted therefrom and now through the perforated bottom 56 into the reservoir I1. The element I5 is formed as a'projecting compressing head 54 which carries a knife 55 that cuts the fruit as` itis being compressed so as to facilitate extraction of the juice.' Said element is further provided withfa rod 5S which extends upwardly therefrom and through a` sleeve 51, the upper end of said rod being threaded to receive the securing nuts 58.l A collar 5t is provided on the rod within the sleeve 51 and interposed between said collar and the closed upper end of the sleeve 51 there is provided a coil spring Se which forms a resilient cushion for the element Iii as the latter is compressing the fruit between it and the bottom 50.' The sleeve 51 is connected by a bracket' 6I to the vertically movable 'slide 62 supported in a guide 63 mounted on the frame i0. Thelower end of the slide t2 has a pin and slot connection with one end of an armed plvotally mounted at 65 on the frame I@ andcarrying, intermediate its ends, a roller E55 adapted for engagement with the groove of a cam 51 mounted on the shaft I9 and rotatable therewith. Said cam is so positioned upon the shaft that the arm @t will start its downward movement about the pivot t5 directly after a fruit has been deposited into the element I4 and after the extraction of the juice from said fruit has been accomplished the cam again raises the arm Se to withdraw the element I5 from engagement with the compressed fruit. YAt the conclusion of this operation the element ifi containing the compressed fruit is swung about its pivot 68 to the dotted line position of Fig. 1 where saidV element contacts a bumper 69 mounted on the discharge chute I5. The element I6 strikes said bumper with considerable force and in this manner dislodges the compressed fruit from said element so that it will fall into said chute, after which the element I4 is restored to the full line position of Fig. 1. This operation is accomplished through the medium of a vertically movable rack bar 10 slldably mounted in a guide 1i carried by the frame i0 with the teeth of said bar engagingapinion 12 fixed on the pivot 58 of the element I4. The lower end' of the bar 1u terminates in a guide 13 in which is disposed .a block 1t having springs 15 disposed on opposite sides thereof to act as shock `absorbers when the element I4 strikes the bumper .69 and is returned to its operative position on top of the funnel 52. Said block 14 is carried by one end of ya long arm 15 the other end of which is. mounted upon the pivot 65 and, intermedateits ends, said arm carries a roller 11 engageable with a cam i8 on the shaft I9. Said cam controls the movement of the arm 16 so as to swing the element toward its discharge position after the element I5 has been raised, and immediately upon the discharge of the compressed fruit said arm 16 then operates to return the element I4 to its original position.

The movements of the arm 1B about its pivot 65 .are also utilized to control vthe discharge of a measured quantity of juice from the reservoir I1 through the medium of the valve structure 20 into one of the receptacles 2| on the turnta-ble 22. lSaid valve structure 2|) comprises a cylindrical, horizontally disposed body attached to the lower end of the reservoir I1 and communicating with an outlet 19 in said reservoir. A sleeve valve is mounted for oscillation within the-body 20 and hasY an opening 8| therein which alternately registers with the outlet.19 and the discharge nozzle 32 in the valve body. With the valve in the position of Fig. 4 and the reservoir I1 lled `with juice above the level of the outlet 19, the

valve 80 will receive a predetermined amount of the juicerfrom the reservoir and when said valve is turned in one direction, as will presently appear, further communication with the reservoir will be temporarily closed and at the termination of said movement of the valve its opening 8| will be registered with the outlet 82in such manner as to permit the juice contained in said valve to iiow into a receptacle 2|, whereupon the valve 80 is turned in the opposite direction to again register its opening 8| with the outlet 19 so that the valve will again be lled. To accomplish this operation, the valve 86 is provided with a rod 83 extending from one end of the body 2|) and connected to one end of anoperating arm 84 the other end of which has a pin and slot connection 85 with'the arm 1S so that as said arm is operated by its cam 13 the operating arm 84 will oscillate to impart a similar movement to the valve 85.

During the various operations thus far Ydescribed the agitator I within the reservoir I1 is constantly rotated by an endless belt 8S extending about a pulley 81 on the shaft 88 of said agitator and also around' a pulley 8@ on the shaft it. v

After a receptacle 2 has been filled with juice from the valve til the turntable 22 is advanced one step to position a succeeding receptacle 2| beneath the nozzle 82 preparatory to a discharge of another measured quantity oi juice from the reservoir. For this purpose the turntable 22 is rotatably supported in a bracket st having a bearing portion 9| through which extends the depending shaft 92 of said turntable. A plate Q3 is carried by the lower end of the shaft 92
